Abstract

A new and distinct cultivar of Torenia plant named ‘Sunrekodebu’, characterized by its compact and mounding to trailing plant habit; freely branching habit; freely flowering habit; dark violet-colored flowers; and good garden performance.

Description

Botanical designation: Torenia sp.

Cultivar denomination: ‘SUNREKODEBU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Torenia plant, botanically known as Torenia sp. and hereinafter referred to by the name ‘Sunrekodebu’.

The new Torenia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new compact and freely branching Torenia plants with numerous attractive flowers.

The new Torenia plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in July, 2007 of a proprietary selection of Torenia sp, identified as code name TP-1, not patented, as the female, or seed, parent with a proprietary selection of Torenia sp. identified as code name TC-V, not patented, as the male, or pollen, parent. The new Torenia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in March, 2008.

Asexual reproduction of the new Torenia plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April, 2008, has shown that the unique features of this new Torenia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Torenia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunrekodebu’. These characteristics in combination distinguish ‘Sunrekodebu’ as a new and distinct cultivar of Torenia:

- 1. Compact and mounding to trailing plant habit.
- 2. Freely branching habit.
- 3. Freely flowering habit.
- 4. Dark violet-colored flowers.
- 5. Good garden performance.

Plants of the new Torenia differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Torenia are more compact than plants of the female parent selection.
- 2. Plants of the new Torenia are more upright than plants of the female parent selection.
- 3. Plants of the new Torenia and the female parent selection differ in flower color as plants of the female parent selection have violet blue-colored flowers.

Plants of the new Torenia differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Torenia are more compact than plants of the male parent selection.
- 2. Plants of the new Torenia are not as upright as plants of the male parent selection.
- 3. Plants of the new Torenia and the male parent selection differ in flower color as plants of the male parent selection have dark violet blue-colored flowers.

Plants of the new Torenia can be compared to plants of Torenia ‘Sunrenilabu’, disclosed in U.S. Plant Pat. No. 10,843. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Torenia and ‘Sunrenilabu’ differed in the following characteristics:

- 1. Plants of the new Torenia were taller and narrower than plants of ‘Sunrenilabu’.
- 2. Plants of the new Torenia were more upright than plants of ‘Sunrenilabu’.
- 3. Plants of the new Torenia had thicker stems and shorter internodes than plants of ‘Sunrenilabu’.
- 4. Plants of the new Torenia flowered earlier than plants of ‘Sunrenilabu’.
- 5. Plants of the new Torenia and ‘Sunrenilabu’ differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Torenia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Torenia plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunrekodebu’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunrekodebu’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical for commercial Torenia production.
